A suicidal 29-year-old ground agent boarded a Horizon Air Bombardier Q400 and made an authorized takeoff from Seattle’s Sea-Tac airport late Friday night, crashing the plane on Ketron island after attempting stunts and communicating with a controller.

The Seattle Times reports: ‘The Sheriff’s Department said it was “not a terrorist incident.” The plane crashed either while the man was doing stunts or because of a lack of flying skills, according to the Sheriff’s Department. “A joyride gone terribly wrong,” Pierce County Sheriff Paul Pastor said during a news conference in Steilacoom, which is about 3 miles from the island. No injuries were reported on the ground, Pastor said, as the plane crashed and started an intense fire on the wooded, 230-acre island, which has a population of 20. He said it appeared the man who took the plane died.’

The SeattlePI adds that the man also said: “I’ve got a lot of people that care about me. It’s going to disappoint them to hear that I did this. I would like to apologize to each and every one of them. Just a broken guy, got a few screws loose, I guess. Never knew it, until now.”
